Dan saw brown fur spread from his arms across the rest of his body, and unseen by him it even created a streak of black fur on his back. "I decided on a German Shepherd. They're very friendly and easy to keep", Kat chuckled. Dan was still looking at his clawed hands, which now started to shrink and fuse into padded paws, just like his feet. Uncomfortably, he thus shook off his oversized shoes and socks, stumbling so much now that he just decided to rest on his forepaws. "Already moving onto all fours? Good boy!", Kat snickered. His face was elongating now, jawbones extending along with his teeth into a sharp-fanged muzzle with a flat black leather nose at the end. The stress of the transformation was already causing him to pant, his new canine tongue on full display. Eyes, ears and skull finally completed the formation of his magnificient head, the transformation now slowly reaching the details.
His entire bone structure was warping, causing him to whimper loudly in pain. His legs shortened to the same length as his arms, and his spine completely straightened out to move him into a quadrupedal position. Dan seemed almost finished now, but seemed to be bracing for something - this appearing as a bulge in his pants, growing larger and larger until the back seams finally tore and a wagging tail came out. "Aww, poor doggie", coddled Kat, "to be stuck in these human things you don't need...here, let me help you", and removed what was left of Dan's clothes, leaving him naked as an indistinguishable German Shepherd. "Now, what to do...", pondered Kat.
